Features and Options
The RMA801 Remote Indicator provides a means of remote-mounting a indicator (display)
that is associated with a Honeywell Smartline Transmitter or any transmitter operating in a
4-20 mA current loop.
The RMA801 is a DE/Analog Remote Indicator which can be connected anywhere along
the current loop.
For analog PV, the RMA801 measures the loop current and displays the equivalent PV
value on the display.
The RMA801 will autoconfigure when connected to Honeywell STT700/STT250 DE
transmitters when a database upload is performed.
This document provides the information for a quick setup. For detailed information, please refer
RMA801 user manual, 34-ST-25-62.

CAUTION
Temperature extremes can affect display quality. The display can go blank if the
temperature is below -20°C or above 70°C; however, this is only a temporary condition. The
display will again be readable when temperatures return to within operable limits.
The device shall be operated by a trained professional. It is the user/installer’s responsibility
to install the indicator in accordance with national and local code requirements. Conduit
entry plugs and adapters shall be suitable for the environment, shall be certified for the
hazardous location when required and acceptable to the authority having jurisdiction for the
plant
The RMA device is always connected in series with the transmitter. The current loop will
be broken if the RMA801 device is removed from the loop.
Installation and setup
Site evaluation
Evaluate the site selected for the Remote Indicator installation with respect to the
process system design specifications and Honeywell’s published performance
characteristics for your particular model. Some parameters that you may want to
include in your site evaluation can be found in the RMA801 user manual, 34-ST-2562
Installation precautions
Temperature extremes can affect display quality. The display can go blank if the
temperature is below -20°C or above +70°C; however, this is only a temporary
condition. The display will again be readable when temperatures return to within
operable limits.
Explosion-Proof Conduit Seal
WARNING
When installed as explosion proof in a Division 1 Hazardous Location, keep
covers tight while the Remote Indicator is energized. Disconnect power to the
Remote Indicator in the non-hazardous area prior to removing end caps for
service.
When installed as non-incendive equipment in a Division 2 hazardous location,
disconnect power to the Remote Indicator in the non-hazardous area, or
determine that the location is non-hazardous before disconnecting or
connecting the Remote Indicator wires.
Mounting Remote indicator
Summary Remote Indicator models can be attached to a two-inch (50.8 millimeter)
vertical or horizontal pipe using Honeywell’s optional pipe mounting bracket. Honeywell’s
optional wall mounting bracket is also shown in figures below.
Mounting Dimensions
Refer to Honeywell drawing number 51455045* for detailed electronic housing
dimensions. Refer to Honeywell drawing numbers 32306827* for detailed pipe mounting
dimensions, 50124813* for Detailed Pipe Angle mounting dimensions and 32306828* for
detailed wall mounting dimensions.
THE TRANSMITTER ENCLOSURE CAN BE ROTATED A TOTAL OF 90° FROM THE
STANDARD MOUNTING POSITION
* Honeywell drawings can be supplied on request.
Bracket Mounting
If you are using an optional bracket, start with Step 1.
1. Pipe Mount Option -Refer to Figure 2. Align the two mounting holes at the
bottom of the Remote Indicator with the two slots in the mounting bracket
and assemble the (2) M8 hex cap screws, (2) lock washers and (2) flat
washers provided.
2. Rotate the Remote Indicator assembly to the desired position and torque the
M8 hex cap screws to 27,0 Nm/20,0 Lb-ft maximum
3. Position the bracket on a 2-inch (50.8 mm) horizontal or vertical pipe, and
install a “U” bolt around the pipe and through the holes in the bracket.
Secure the bracket with (2) M10 hex nuts, (2) flat washers and (2) lock
washers provided. Refer to Figure 4.

Wall Mount Option – Refer Figure 5 Position the bracket on the mounting
surface at the desired location and secure the bracket to the mounting
surface using the appropriate hardware (Wall mounting hardware
requirements to be determined and supplied by the end user).

Wiring a Remote Indicator
Overview
The Remote Indicator is designed to operate in normal 4-20mA analog mode with HART
enabled transmitters across SmartLine Devices. In DE mode, only STT250 and STT700
Honeywell SmartLine transmitters.
For improved noise performance, it is recommended to provide earth ground for both
transmitter and RMA housing.
Figure 6: DE/ANALOG Terminal Block
Figure 7: RMA801 Terminal Block
Terminal Block
The RMA801 has 3 terminals. Following table provides the connection details-
Three screw terminals suitable for wirings up to (16AWG)
Shielded, twisted-pair cable such as Belden 9318 or equivalent must be used for
all signal/power wiring.
The cable shield must be connected at only one end of the cable. Connect it to
the power supply side and leave the shield insulated at the transmitter side
and RMA side.
Loop Terminals 5 & 6 shall be connected in series with the 4-20 ma loop for both analog
and DE modes. Additionally, third wire (Terminal 9) is required for DE communication in
DE mode only.
Loop wiring for analog and DE mode is shown in figure below.
NOTE:
After wiring the Transmitter as outline in the next sections, torque the screws to
1.1 Nm (10 lb-in)
Terminal No.
